Bana The extractor rin is an aggravation relatesto the extractor'ii'ng and rotatabl mounted a circunb' ove int bolt formingthe suprv fjf ort fdr t semester which is a longitudirin m'ember'having ahook at its forwe: on to engage with and draw the exlfigoddywcartridge. Heretofore the extractor '1 has commonly been made of one piece and bent to shape around the bolt 1 and secured by its meeting ends to the ex- 1mm. Since the ring must fit the dgroove 't'ql snugly and must also be easily rotate there- 'the manufacture and assembly ef these "16 piece bands, as also their repalrywhen are fairl diflicult operations.

to t is invention the manufacand assemblyof such rings is simpliand their cost reduced. The new ring 1s I made up of a plurality of parts each of which i'a' roperly curved before assembly on the Y. and so formed that it can be uickly sh bled with the other parts to. 201m a support for the extractor. -These ring 'rts ma be two in number and each I E: a dup 'cate of the'otherisofthat the vrings can be cheaply made; they maybe pro as in pressing or stamping machines.

' cartridge hook .21 and ailug20 bywhich it engages the groove 13 in the bolt, to be thereby normallyheld 3%111817 longitudinal disp acement thereon.

ear its middlethe ex-f tractor is thickened and formed with a longitudinalT-slot 17 by which itengages and draws together the ends of the extractor ring. This slot is openatits rear end so that 1t .may be pushed rearwardly over the ends of the ring toth'e' plosition of Fig. 2 inwhich it is retained by t e engagement ,of the In 20111 groove 13. Between its middle and endsthe extractor bar is thin in order to be elastic. In the assembled position it will be understood that the lug 20 rides in the groove 13 as the bolt rotates while the hook 21 extends radially over the forward edge of the bolt and is ada ted to snap over the rim of the cartridge w. en the bolt is locked up. I f

The extractor ring comprises a plurality of complementary parts; preferably the parts are similar so far as may be, and preflike '25 and 26 of identical size and s ape.

Each of the ring parts, of whatever shape and number, is made with an interior curvature of substantially the same radius as the bottom of the groove and of a corresponding width and thickness. They are inserted in the groove 15 and there fastened together in any suitable way to form the whole ring, and are preferably fastened by an interlocking joint (Fig. '3' constituted of a notch 27 formed in the e ge of each part to receive 7 the hook 28 of the other. The opposite ends same as prior one-piece rings, but has the advantages above mentioned. It will be apparent that the principle of the invention can be applied in different ways to difierent tvpes of bolts and extractors, there bein no limitation to the particular mechanism a ove taken for illustration.
